Conventions for Designation of Variants

For purposes of the present invention, the polypeptide disclosed in SEQID NO: 3 is used to determine the corresponding amino acid residue inanother lipase. The amino acid sequence of another lipase is alignedwith SEQ ID NO: 3, and based on the alignment, the amino acid positionnumber corresponding to any amino acid residue in SEQ ID NO: 3 isdetermined using the Needleman-Wunsch algorithm (Needleman and Wunsch,1970, J. Mol. Biol. 48: 443-453) as implemented in the Needle program ofthe EMBOSS package (EMBOSS: The European Molecular Biology Open SoftwareSuite, Rice et al., 2000, Trends Genet. 16: 276-277), preferably version5.0.0 or later. The parameters used are gap open penalty of 10, gapextension penalty of 0.5, and the EBLOSUM62 (EMBOSS version of BLOSUM62)substitution matrix.

Identification of the corresponding amino acid residue in another lipasecan be determined by an alignment of multiple polypeptide sequencesusing several computer programs including, but not limited to, MUSCLE(multiple sequence comparison by log-expectation; version 3.5 or later;Edgar, 2004, Nucleic Acids Research 32: 1792-1797), MAFFT (version 6.857or later; Katoh and Kuma, 2002, Nucleic Acids Research 30: 3059-3066;Katoh et al., 2005, Nucleic Acids Research 33: 511-518; Katoh and Toh,2007, Bioinformatics 23: 372-374; Katoh et al., 2009, Methods inMolecular Biology 537:_39-64; Katoh and Toh, 2010, Bioinformatics26:_1899-1900), and EMBOSS EMMA employing ClustalW (1.83 or later;Thompson et al., 1994, Nucleic Acids Research 22: 4673-4680), usingtheir respective default parameters.

When the other enzyme has diverged from the polypeptide of SEQ ID NO: 3such that traditional sequence-based comparison fails to detect theirrelationship (Lindahl and Elofsson, 2000, J. Mol. Biol. 295: 613-615),other pairwise sequence comparison algorithms can be used. Greatersensitivity in sequence-based searching can be attained using searchprograms that utilize probabilistic representations of polypeptidefamilies (profiles) to search databases. For example, the PSI-BLASTprogram generates profiles through an iterative database search processand is capable of detecting remote homologs (Atschul et al., 1997,Nucleic Acids Res. 25: 3389-3402). Even greater sensitivity can beachieved if the family or superfamily for the polypeptide has one ormore representatives in the protein structure databases. Programs suchas GenTHREADER (Jones, 1999, J. Mol. Biol. 287: 797-815; McGuffin andJones, 2003, Bioinformatics 19: 874-881) utilize information from avariety of sources (PSI-BLAST, secondary structure prediction,structural alignment profiles, and solvation potentials) as input to aneural network that predicts the structural fold for a query sequence.Similarly, the method of Gough et al., 2000, J. Mol. Biol. 313: 903-919,can be used to align a sequence of unknown structure with thesuperfamily models present in the SCOP database. These alignments can inturn be used to generate homology models for the polypeptide, and suchmodels can be assessed for accuracy using a variety of tools developedfor that purpose.

For proteins of known structure, several tools and resources areavailable for retrieving and generating structural alignments. Forexample the SCOP superfamilies of proteins have been structurallyaligned, and those alignments are accessible and downloadable. Two ormore protein structures can be aligned using a variety of algorithmssuch as the distance alignment matrix (Holm and Sander, 1998, Proteins33: 88-96) or combinatorial extension (Shindyalov and Bourne, 1998,Protein Engineering 11: 739-747), and implementation of these algorithmscan additionally be utilized to query structure databases with astructure of interest in order to discover possible structural homologs(e.g., Holm and Park, 2000, Bioinformatics 16: 566-567).

In describing the variants of the present invention, the nomenclaturedescribed below is adapted for ease of reference. The accepted IUPACsingle letter or three letter amino acid abbreviation is employed.

Substitutions.

For an amino acid substitution, the following nomenclature is used:Original amino acid, position, substituted amino acid. Accordingly, thesubstitution of threonine at position 226 with alanine is designated as“Thr226Ala” or “T226A”. Multiple mutations are separated by additionmarks (“+”), e.g., “Gly205Arg+Ser411Phe” or “G205R+S411F”, representingsubstitutions at positions 205 and 411 of glycine (G) with arginine (R)and serine (S) with phenylalanine (F), respectively.

Deletions.

For an amino acid deletion, the following nomenclature is used: Originalamino acid, position, *. Accordingly, the deletion of glycine atposition 195 is designated as “Gly195*” or “G195*”. Multiple deletionsare separated by addition marks (“+”), e.g., “Gly195*+Ser411*” or“G195*+S411*”.

Insertions.

For an amino acid insertion, the following nomenclature is used:Original amino acid, position, original amino acid, inserted amino acid.Accordingly the insertion of lysine after glycine at position 195 isdesignated “Gly195GlyLys” or “G195GK”. An insertion of multiple aminoacids is designated [Original amino acid, position, original amino acid,inserted amino acid #1, inserted amino acid #2; etc.]. For example, theinsertion of lysine and alanine after glycine at position 195 isindicated as “Gly195GlyLysAla” or “G195GKA”.

In such cases the inserted amino acid residue(s) are numbered by theaddition of lower case letters to the position number of the amino acidresidue preceding the inserted amino acid residue(s). In the aboveexample, the sequence would thus be:

Parent: Variant: 195 195 195a 195b G G - K - A

Multiple Alterations.

Variants comprising multiple alterations are separated by addition marks(“+”), e.g., “Arg170Tyr+Gly195Glu” or “R170Y+G195E” representing asubstitution of arginine and glycine at positions 170 and 195 withtyrosine and glutamic acid, respectively.

Different Alterations.

Where different alterations can be introduced at a position, thedifferent alterations are separated by a comma, e.g., “Arg170Tyr,Glu”represents a substitution of arginine at position 170 with tyrosine orglutamic acid. Thus, “Tyr167Gly,Ala+Arg170Gly,Ala” designates thefollowing variants: “Tyr167Gly+Arg170Gly”, “Tyr167Gly+Arg170Ala”,“Tyr167Ala+Arg170Gly”, and “Tyr167Ala+Arg170Ala”.

The improved property may be measured by “D Stability inDetergent Assay” as described in Example 1.

The variants may further comprise one or more additional substitutionsat one or more (e.g., several) other positions.

The amino acid changes may be of a minor nature, that is conservativeamino acid substitutions or insertions that do not significantly affectthe folding and/or activity of the protein; small deletions, typicallyof 1-30 amino acids; small amino- or carboxyl-terminal extensions, suchas an amino-terminal methionine residue; a small linker peptide of up to20-25 residues; or a small extension that facilitates purification bychanging net charge or another function, such as a poly-histidine tract,an antigenic epitope or a binding domain.

Examples of conservative substitutions are within the groups of basicamino acids (arginine, lysine and histidine), acidic amino acids(glutamic acid and aspartic acid), polar amino acids (glutamine andasparagine), hydrophobic amino acids (leucine, isoleucine and valine),aromatic amino acids (phenylalanine, tryptophan and tyrosine), and smallamino acids (glycine, alanine, serine, threonine and methionine). Aminoacid substitutions that do not generally alter specific activity areknown in the art and are described, for example, by H. Neurath and R. L.Hill, 1979, In, The Proteins, Academic Press, New York. Commonsubstitutions are Ala/Ser, Val/Ile, Asp/Glu, Thr/Ser, Ala/Gly, Ala/Thr,Ser/Asn, Ala/Val, Ser/Gly, Tyr/Phe, Ala/Pro, Lys/Arg, Asp/Asn, Leu/Ile,Leu/Val, Ala/Glu, and Asp/Gly.

Alternatively, the amino acid changes are of such a nature that thephysico-chemical properties of the polypeptides are altered. Forexample, amino acid changes may improve the thermal stability of thepolypeptide, alter the substrate specificity, change the pH optimum, andthe like.

For example, the variants may further comprise a substitution at one ormore positions corresponding to: A8T; Y28LC; I41T; C43S; D48E; K50E;Y60AC; D61NKRAVLSTC; R80C; S84C; I86C; N87C; A90C; D91NKRAVLST; F94LTK;S98P; S103R; D113NKRAVLST; S114C; G116V; N120KD; K131F; G156D; N186Y;E201QKRAVLST; I204VATSG; V205IL; L208VATSG; F213VATSG; H217N;D226NKRAVLST; T236A; T241S; D243NKRAVLSTH; V254IATSG; L255VATSG;D256NKRAVLST; L258VATSG; Y260WCGV; L267VATSG of SEQ ID NO: 3.

Essential amino acids in a polypeptide can be identified according toprocedures known in the art, such as site-directed mutagenesis oralanine-scanning mutagenesis (Cunningham and Wells, 1989, Science 244:1081-1085). In the latter technique, single alanine mutations areintroduced at every residue in the molecule, and the resultant mutantmolecules are tested for lipase activity to identify amino acid residuesthat are critical to the activity of the molecule. See also, Hilton etal., 1996, J. Biol. Chem. 271: 4699-4708. The active site of the enzymeor other biological interaction can also be determined by physicalanalysis of structure, as determined by such techniques as nuclearmagnetic resonance, crystallography, electron diffraction, orphotoaffinity labeling, in conjunction with mutation of putative contactsite amino acids. See, for example, de Vos et al., 1992, Science 255:306-312; Smith et al., 1992, J. Mol. Biol. 224: 899-904; Wlodaver etal., 1992, FEBS Lett. 309: 59-64. The identity of essential amino acidscan also be inferred from an alignment with a related polypeptide.

In an aspect, the parent has a sequence identity to SEQ ID NO: 3 of atleast 75%, e.g., at least 80%, at least 85%, at least 90%, at least 91%,at least 92%, at least 93%, at least 94%, at least 95%, at least 96%, atleast 97%, at least 98%, at least 99%, or 100%, which have lipaseactivity. In one aspect, the amino acid sequence of the parent differsby up to 40 amino acids, e.g., 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12,13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30,31, 32, 33, 34, 35, 36, 37, 38, 39, or 40 from SEQ ID NO: 3.

The polynucleotide of SEQ ID NO: 1 or a subsequence thereof, as well asthe polypeptide of SEQ ID NO: 2 or a fragment thereof, may be used todesign nucleic acid probes to identify and clone DNA encoding a parentfrom strains of different genera or species according to methods wellknown in the art. In particular, such probes can be used forhybridization with the genomic DNA or cDNA of a cell of interest,following standard Southern blotting procedures, in order to identifyand isolate the corresponding gene therein. Such probes can beconsiderably shorter than the entire sequence, but should be at least15, e.g., at least 25, at least 35, or at least 70 nucleotides inlength. Preferably, the nucleic acid probe is at least 100 nucleotidesin length, e.g., at least 200 nucleotides, at least 300 nucleotides, atleast 400 nucleotides, at least 500 nucleotides, at least 600nucleotides, at least 700 nucleotides, at least 800 nucleotides, or atleast 900 nucleotides in length. Both DNA and RNA probes can be used.The probes are typically labeled for detecting the corresponding gene(for example, with ³²P, ³H, ³⁵S, biotin, or avidin). Such probes areencompassed by the present invention.

A genomic DNA or cDNA library prepared from such other strains may bescreened for DNA that hybridizes with the probes described above andencodes a parent. Genomic or other DNA from such other strains may beseparated by agarose or polyacrylamide gel electrophoresis, or otherseparation techniques. DNA from the libraries or the separated DNA maybe transferred to and immobilized on nitrocellulose or other suitablecarrier material. In order to identify a clone or DNA that hybridizeswith SEQ ID NO: 1 or a subsequence thereof, the carrier material is usedin a Southern blot.

For purposes of the present invention, hybridization indicates that thepolynucleotide hybridizes to a labeled nucleic acid probe correspondingto (i) SEQ ID NO: 1; (ii) the mature polypeptide coding sequence of SEQID NO: 1; (iii) the full-length complement thereof; or (iv) asubsequence thereof; under very low to very high stringency conditions.Molecules to which the nucleic acid probe hybridizes under theseconditions can be detected using, for example, X-ray film or any otherdetection means known in the art.

In another aspect, the nucleicacid probe is a polynucleotide that encodes the polypeptide of SEQ IDNO: 2; the mature polypeptide thereof; or a fragment thereof. In anotheraspect, the nucleic acid probe is SEQ ID NO: 1.

In another embodiment, the parent is encoded by a polynucleotide havinga sequence identity to the mature polypeptide coding sequence of SEQ IDNO: 1 of at least 60%, e.g., at least 65%, at least 70%, at least 75%,at least 80%, at least 85%, at least 90%, at least 91%, at least 92%, atleast 93%, at least 94%, at least 95%, at least 96%, at least 97%, atleast 98%, at least 99%, or 100%.

The parent may be a fusion polypeptide or cleavable fusion polypeptidein which another polypeptide is fused at the N-terminus or theC-terminus of the polypeptide of the present invention. A fusionpolypeptide is produced by fusing a polynucleotide encoding anotherpolypeptide to a polynucleotide of the present invention. Techniques forproducing fusion polypeptides are known in the art, and include ligatingthe coding sequences encoding the polypeptides so that they are in frameand that expression of the fusion polypeptide is under control of thesame promoter(s) and terminator. Fusion polypeptides may also beconstructed using intein technology in which fusion polypeptides arecreated post-translationally (Cooper et al., 1993, EMBO J. 12:2575-2583; Dawson et al., 1994, Science 266: 776-779).

A fusion polypeptide can further comprise a cleavage site between thetwo polypeptides. Upon secretion of the fusion protein, the site iscleaved releasing the two polypeptides. Examples of cleavage sitesinclude, but are not limited to, the sites disclosed in Martin et al.,2003, J. Ind. Microbiol. Biotechnol. 3: 568-576; Svetina et al., 2000,J. Biotechnol. 76: 245-251; Rasmussen-Wilson et al., 1997, Appl.Environ. Microbiol. 63: 3488-3493; Ward et al., 1995, Biotechnology 13:498-503; and Contreras et al., 1991, Biotechnology 9: 378-381; Eaton etal., 1986, Biochemistry 25: 505-512; Collins-Racie et al., 1995,Biotechnology 13: 982-987; Carter et al., 1989, Proteins: Structure,Function, and Genetics 6: 240-248; and Stevens, 2003, Drug DiscoveryWorld 4: 35-48.

The variants can be prepared using any mutagenesis procedure known inthe art, such as site-directed mutagenesis, synthetic gene construction,semi-synthetic gene construction, random mutagenesis, shuffling, etc.

Site-directed mutagenesis is a technique in which one or more (e.g.,several) mutations are introduced at one or more defined sites in apolynucleotide encoding the parent.

Site-directed mutagenesis can be accomplished in vitro by PCR involvingthe use of oligonucleotide primers containing the desired mutation.Site-directed mutagenesis can also be performed in vitro by cassettemutagenesis involving the cleavage by a restriction enzyme at a site inthe plasmid comprising a polynucleotide encoding the parent andsubsequent ligation of an oligonucleotide containing the mutation in thepolynucleotide. Usually the restriction enzyme that digests the plasmidand the oligonucleotide is the same, permitting sticky ends of theplasmid and the insert to ligate to one another. See, e.g., Scherer andDavis, 1979, Proc. Natl. Acad. Sci. USA 76: 4949-4955; and Barton etal., 1990, Nucleic Acids Res. 18: 7349-4966.

Site-directed mutagenesis can also be accomplished in vivo by methodsknown in the art. See, e.g., U.S. Patent Application Publication No.2004/0171154; Storici et al., 2001, Nature Biotechnol. 19: 773-776; Krenet al., 1998, Nat. Med. 4: 285-290; and Calissano and Macino, 1996,Fungal Genet. Newslett. 43: 15-16.

Any site-directed mutagenesis procedure can be used in the presentinvention. There are many commercial kits available that can be used toprepare variants.

Synthetic gene construction entails in vitro synthesis of a designedpolynucleotide molecule to encode a polypeptide of interest. Genesynthesis can be performed utilizing a number of techniques, such as themultiplex microchip-based technology described by Tian et al. (2004,Nature 432: 1050-1054) and similar technologies wherein oligonucleotidesare synthesized and assembled upon photo-programmable microfluidicchips.

Single or multiple amino acid substitutions, deletions, and/orinsertions can be made and tested using known methods of mutagenesis,recombination, and/or shuffling, followed by a relevant screeningprocedure, such as those disclosed by Reidhaar-Olson and Sauer, 1988,Science 241: 53-57; Bowie and Sauer, 1989, Proc. Natl. Acad. Sci. USA86: 2152-2156; WO95/17413; or WO95/22625. Other methods that can be usedinclude error-prone PCR, phage display (e.g., Lowman et al., 1991,Biochemistry 30: 10832-10837; U.S. Pat. No. 5,223,409; WO92/06204) andregion-directed mutagenesis (Derbyshire et al., 1986, Gene 46: 145; Neret al., 1988, DNA 7: 127).

Mutagenesis/shuffling methods can be combined with high-throughput,automated screening methods to detect activity of cloned, mutagenizedpolypeptides expressed by host cells (Ness et al., 1999, NatureBiotechnology 17: 893-896). Mutagenized DNA molecules that encode activepolypeptides can be recovered from the host cells and rapidly sequencedusing standard methods in the art. These methods allow the rapiddetermination of the importance of individual amino acid residues in apolypeptide.

Semi-synthetic gene construction is accomplished by combining aspects ofsynthetic gene construction, and/or site-directed mutagenesis, and/orrandom mutagenesis, and/or shuffling. Semi-synthetic construction istypified by a process utilizing polynucleotide fragments that aresynthesized, in combination with PCR techniques. Defined regions ofgenes may thus be synthesized de novo, while other regions may beamplified using site-specific mutagenic primers, while yet other regionsmay be subjected to error-prone PCR or non-error prone PCRamplification. Polynucleotide subsequences may then be shuffled.

Polynucleotides

The present invention also relates to polynucleotides encoding a variantof the present invention.

Nucleic Acid Constructs

The present invention also relates to nucleic acid constructs comprisinga polynucleotide encoding a variant of the present invention operablylinked to one or more control sequences that direct the expression ofthe coding sequence in a suitable host cell under conditions compatiblewith the control sequences.

The polynucleotide may be manipulated in a variety of ways to providefor expression of a variant. Manipulation of the polynucleotide prior toits insertion into a vector may be desirable or necessary depending onthe expression vector. The techniques for modifying polynucleotidesutilizing recombinant DNA methods are well known in the art.

The control sequence may be a promoter, a polynucleotide which isrecognized by a host cell for expression of the polynucleotide. Thepromoter contains transcriptional control sequences that mediate theexpression of the variant. The promoter may be any polynucleotide thatshows transcriptional activity in the host cell including mutant,truncated, and hybrid promoters, and may be obtained from genes encodingextracellular or intracellular polypeptides either homologous orheterologous to the host cell.

Examples of suitable promoters for directing transcription of thenucleic acid constructs of the present invention in a bacterial hostcell are the promoters obtained from the Bacillus amyloliquefaciensalpha-amylase gene (amyQ), Bacillus licheniformis alpha-amylase gene(amyL), Bacillus licheniformis penicillinase gene (penP), Bacillusstearothermophilus maltogenic amylase gene (amyM), Bacillus subtilislevansucrase gene (sacB), Bacillus subtilis xylA and xylB genes,Bacillus thuringiensis cryIIIA gene (Agaisse and Lereclus, 1994,Molecular Microbiology 13: 97-107), E. coli lac operon, E. coli trcpromoter (Egon et al., 1988, Gene 69: 301-315), Streptomyces coelicoloragarase gene (dagA), and prokaryotic beta-lactamase gene (Villa-Kamaroffet al., 1978, Proc. Natl. Acad. Sci. USA 75: 3727-3731), as well as thetac promoter (DeBoer et al., 1983, Proc. Natl. Acad. Sci. USA 80:21-25). Further promoters are described in “Useful proteins fromrecombinant bacteria” in Gilbert et al., 1980, Scientific American 242:74-94; and in Sambrook et al., 1989, supra. Examples of tandem promotersare disclosed in WO 99/43835.

Examples of suitable promoters for directing transcription of thenucleic acid constructs of the present invention in a filamentous fungalhost cell are promoters obtained from the genes for Aspergillus nidulansacetamidase, Aspergillus niger neutral alpha-amylase, Aspergillus nigeracid stable alpha-amylase, Aspergillus niger or Aspergillus awamoriglucoamylase (glaA), Aspergillus oryzae TAKA amylase, Aspergillus oryzaealkaline protease, Aspergillus oryzae triose phosphate isomerase,Fusarium oxysporum trypsin-like protease (WO96/00787), Fusariumvenenatum amyloglucosidase (WO00/56900), Fusarium venenatum Daria(WO00/56900), Fusarium venenatum Quinn (WO00/56900), Rhizomucor mieheilipase, Rhizomucor miehei aspartic proteinase, Trichoderma reeseibeta-glucosidase, Trichoderma reesei cellobiohydrolase I, Trichodermareesei cellobiohydrolase II, Trichoderma reesei endoglucanase I,Trichoderma reesei endoglucanase II, Trichoderma reesei endoglucanaseIII, Trichoderma reesei endoglucanase IV, Trichoderma reeseiendoglucanase V, Trichoderma reesei xylanase I, Trichoderma reeseixylanase II, Trichoderma reesei beta-xylosidase, as well as the NA2-tpipromoter (a modified promoter from an Aspergillus neutral alpha-amylasegene in which the untranslated leader has been replaced by anuntranslated leader from an Aspergillus triose phosphate isomerase gene;non-limiting examples include modified promoters from an Aspergillusniger neutral alpha-amylase gene in which the untranslated leader hasbeen replaced by an untranslated leader from an Aspergillus nidulans orAspergillus oryzae triose phosphate isomerase gene); and mutant,truncated, and hybrid promoters thereof.

In a yeast host, useful promoters are obtained from the genes forSaccharomyces cerevisiae enolase (ENO-1), Saccharomyces cerevisiaegalactokinase (GAL1), Saccharomyces cerevisiae alcoholdehydrogenase/glyceraldehyde-3-phosphate dehydrogenase (ADH1, ADH2/GAP),Saccharomyces cerevisiae triose phosphate isomerase (TPI), Saccharomycescerevisiae metallothionein (CUP1), and Saccharomyces cerevisiae3-phosphoglycerate kinase. Other useful promoters for yeast host cellsare described by Romanos et al., 1992, Yeast 8: 423-488.

The control sequence may also be a transcription terminator, which isrecognized by a host cell to terminate transcription. The terminatorsequence is operably linked to the 3′-terminus of the polynucleotideencoding the variant. Any terminator that is functional in the host cellmay be used.

Preferred terminators for bacterial host cells are obtained from thegenes for Bacillus clausii alkaline protease (aprH), Bacilluslicheniformis alpha-amylase (amyL), and Escherichia coli ribosomal RNA(rrnB).

Preferred terminators for filamentous fungal host cells are obtainedfrom the genes for Aspergillus nidulans anthranilate synthase,Aspergillus niger glucoamylase, Aspergillus niger alpha-glucosidase,Aspergillus oryzae TAKA amylase, and Fusarium oxysporum trypsin-likeprotease.

Preferred terminators for yeast host cells are obtained from the genesfor Saccharomyces cerevisiae enolase, Saccharomyces cerevisiaecytochrome C (CYC1), and Saccharomyces cerevisiaeglyceraldehyde-3-phosphate dehydrogenase. Other useful terminators foryeast host cells are described by Romanos et al., 1992, supra.

The control sequence may also be an mRNA stabilizer region downstream ofa promoter and upstream of the coding sequence of a gene which increasesexpression of the gene.

Examples of suitable mRNA stabilizer regions are obtained from aBacillus thuringiensis ctyIIIA gene (WO94/25612) and a Bacillus subtilisSP82 gene (Hue et al., 1995, Journal of Bacteriology 177: 3465-3471).

The control sequence may also be a leader, a nontranslated region of anmRNA that is important for translation by the host cell. The leadersequence is operably linked to the 5′-terminus of the polynucleotideencoding the variant. Any leader that is functional in the host cell maybe used.

Preferred leaders for filamentous fungal host cells are obtained fromthe genes for Aspergillus oryzae TAKA amylase and Aspergillus nidulanstriose phosphate isomerase.

Suitable leaders for yeast host cells are obtained from the genes forSaccharomyces cerevisiae enolase (ENO-1), Saccharomyces cerevisiae3-phosphoglycerate kinase, Saccharomyces cerevisiae alpha-factor, andSaccharomyces cerevisiae alcoholdehydrogenase/glyceraldehyde-3-phosphate dehydrogenase (ADH2/GAP).

The control sequence may also be a polyadenylation sequence, a sequenceoperably linked to the 3′-terminus of the variant-encoding sequence and,when transcribed, is recognized by the host cell as a signal to addpolyadenosine residues to transcribed mRNA. Any polyadenylation sequencethat is functional in the host cell may be used.

Preferred polyadenylation sequences for filamentous fungal host cellsare obtained from the genes for Aspergillus nidulans anthranilatesynthase, Aspergillus niger glucoamylase, Aspergillus nigeralpha-glucosidase, Aspergillus oryzae TAKA amylase, and Fusariumoxysporum trypsin-like protease.

Useful polyadenylation sequences for yeast host cells are described byGuo and Sherman, 1995, Mol. Cellular Biol. 15: 5983-5990.

The control sequence may also be a signal peptide coding region thatencodes a signal peptide linked to the N-terminus of a variant anddirects the variant into the cell's secretory pathway. The 5′-end of thecoding sequence of the polynucleotide may inherently contain a signalpeptide coding sequence naturally linked in translation reading framewith the segment of the coding sequence that encodes the variant.Alternatively, the 5′-end of the coding sequence may contain a signalpeptide coding sequence that is foreign to the coding sequence. Aforeign signal peptide coding sequence may be required where the codingsequence does not naturally contain a signal peptide coding sequence.Alternatively, a foreign signal peptide coding sequence may simplyreplace the natural signal peptide coding sequence in order to enhancesecretion of the variant. However, any signal peptide coding sequencethat directs the expressed variant into the secretory pathway of a hostcell may be used.

Effective signal peptide coding sequences for bacterial host cells arethe signal peptide coding sequences obtained from the genes for BacillusNCIB 11837 maltogenic amylase, Bacillus licheniformis subtilisin,Bacillus licheniformis beta-lactamase, Bacillus stearothermophilusalpha-amylase, Bacillus stearothermophilus neutral proteases (nprT,nprS, nprM), and Bacillus subtilis prsA. Further signal peptides aredescribed by Simonen and Palva, 1993, Microbiological Reviews 57:109-137.

Effective signal peptide coding sequences for filamentous fungal hostcells are the signal peptide coding sequences obtained from the genesfor Aspergillus niger neutral amylase, Aspergillus niger glucoamylase,Aspergillus oryzae TAKA amylase, Humicola insolens cellulase, Humicolainsolens endoglucanase V, Humicola lanuginosa lipase, and Rhizomucormiehei aspartic proteinase.

Useful signal peptides for yeast host cells are obtained from the genesfor Saccharomyces cerevisiae alpha-factor and Saccharomyces cerevisiaeinvertase. Other useful signal peptide coding sequences are described byRomanos et al., 1992, supra.

The control sequence may also be a propeptide coding sequence thatencodes a propeptide positioned at the N-terminus of a variant. Theresultant polypeptide is known as a proenzyme or propolypeptide (or azymogen in some cases). A propolypeptide is generally inactive and canbe converted to an active polypeptide by catalytic or autocatalyticcleavage of the propeptide from the propolypeptide. The propeptidecoding sequence may be obtained from the genes for Bacillus subtilisalkaline protease (aprE), Bacillus subtilis neutral protease (nprT),Myceliophthora thermophila laccase (WO95/33836), Rhizomucor mieheiaspartic proteinase, and Saccharomyces cerevisiae alpha-factor.

Where both signal peptide and propeptide sequences are present, thepropeptide sequence is positioned next to the N-terminus of the variantand the signal peptide sequence is positioned next to the N-terminus ofthe propeptide sequence.

It may also be desirable to add regulatory sequences that regulateexpression of the variant relative to the growth of the host cell.Examples of regulatory systems are those that cause expression of thegene to be turned on or off in response to a chemical or physicalstimulus, including the presence of a regulatory compound. Regulatorysystems in prokaryotic systems include the lac, tac, and trp operatorsystems. In yeast, the ADH2 system or GAL1 system may be used. Infilamentous fungi, the Aspergillus niger glucoamylase promoter,Aspergillus oryzae TAKA alpha-amylase promoter, and Aspergillus oryzaeglucoamylase promoter may be used. Other examples of regulatorysequences are those that allow for gene amplification. In eukaryoticsystems, these regulatory sequences include the dihydrofolate reductasegene that is amplified in the presence of methotrexate, and themetallothionein genes that are amplified with heavy metals. In thesecases, the polynucleotide encoding the variant would be operably linkedwith the regulatory sequence.

Expression Vectors

The present invention also relates to recombinant expression vectorscomprising a polynucleotide encoding a variant of the present invention,a promoter, and transcriptional and translational stop signals. Thevarious nucleotide and control sequences may be joined together toproduce a recombinant expression vector that may include one or moreconvenient restriction sites to allow for insertion or substitution ofthe polynucleotide encoding the variant at such sites. Alternatively,the polynucleotide may be expressed by inserting the polynucleotide or anucleic acid construct comprising the polynucleotide into an appropriatevector for expression. In creating the expression vector, the codingsequence is located in the vector so that the coding sequence isoperably linked with the appropriate control sequences for expression.

The recombinant expression vector may be any vector (e.g., a plasmid orvirus) that can be conveniently subjected to recombinant DNA proceduresand can bring about expression of the polynucleotide. The choice of thevector will typically depend on the compatibility of the vector with thehost cell into which the vector is to be introduced. The vector may be alinear or closed circular plasmid.

The vector may be an autonomously replicating vector, i.e., a vectorthat exists as an extrachromosomal entity, the replication of which isindependent of chromosomal replication, e.g., a plasmid, anextrachromosomal element, a minichromosome, or an artificial chromosome.The vector may contain any means for assuring self-replication.Alternatively, the vector may be one that, when introduced into the hostcell, is integrated into the genome and replicated together with thechromosome(s) into which it has been integrated. Furthermore, a singlevector or plasmid or two or more vectors or plasmids that togethercontain the total DNA to be introduced into the genome of the host cell,or a transposon, may be used.

The vector preferably contains one or more selectable markers thatpermit easy selection of transformed, transfected, transduced, or thelike cells. A selectable marker is a gene the product of which providesfor biocide or viral resistance, resistance to heavy metals, prototrophyto auxotrophs, and the like.

Examples of bacterial selectable markers are Bacillus licheniformis orBacillus subtilis dal genes, or markers that confer antibioticresistance such as ampicillin, chloramphenicol, kanamycin, neomycin,spectinomycin or tetracycline resistance. Suitable markers for yeasthost cells include, but are not limited to, ADE2, HIS3, LEU2, LYS2,MET3, TRP1, and URA3. Selectable markers for use in a filamentous fungalhost cell include, but are not limited to, amdS (acetamidase), argB(ornithine carbamoyltransferase), bar (phosphinothricinacetyltransferase), hph (hygromycin phosphotransferase), niaD (nitratereductase), pyrG (orotidine-5′-phosphate decarboxylase), sC (sulfateadenyltransferase), and trpC (anthranilate synthase), as well asequivalents thereof. Preferred for use in an Aspergillus cell areAspergillus nidulans or Aspergillus oryzae amdS and pyrG genes and aStreptomyces hygroscopicus bar gene.

The vector preferably contains an element(s) that permits integration ofthe vector into the host cell's genome or autonomous replication of thevector in the cell independent of the genome.

For integration into the host cell genome, the vector may rely on thepolynucleotide's sequence encoding the variant or any other element ofthe vector for integration into the genome by homologous ornon-homologous recombination. Alternatively, the vector may containadditional polynucleotides for directing integration by homologousrecombination into the genome of the host cell at a precise location(s)in the chromosome(s). To increase the likelihood of integration at aprecise location, the integrational elements should contain a sufficientnumber of nucleic acids, such as 100 to 10,000 base pairs, 400 to 10,000base pairs, and 800 to 10,000 base pairs, which have a high degree ofsequence identity to the corresponding target sequence to enhance theprobability of homologous recombination. The integrational elements maybe any sequence that is homologous with the target sequence in thegenome of the host cell. Furthermore, the integrational elements may benon-encoding or encoding polynucleotides. On the other hand, the vectormay be integrated into the genome of the host cell by non-homologousrecombination.

For autonomous replication, the vector may further comprise an origin ofreplication enabling the vector to replicate autonomously in the hostcell in question. The origin of replication may be any plasmidreplicator mediating autonomous replication that functions in a cell.The term “origin of replication” or “plasmid replicator” means apolynucleotide that enables a plasmid or vector to replicate in vivo.

Examples of bacterial origins of replication are the origins ofreplication of plasmids pBR322, pUC19, pACYC177, and pACYC184 permittingreplication in E. coli, and pUB110, pE194, pTA1060, and pAMR1 permittingreplication in Bacillus.

Examples of origins of replication for use in a yeast host cell are the2 micron origin of replication, ARS1, ARS4, the combination of ARS1 andCEN3, and the combination of ARS4 and CEN6.

Examples of origins of replication useful in a filamentous fungal cellare AMA1 and ANSI (Gems et al., 1991, Gene 98: 61-67; Cullen et al.,1987, Nucleic Acids Res. 15: 9163-9175; WO00/24883). Isolation of theAMA1 gene and construction of plasmids or vectors comprising the genecan be accomplished according to the methods disclosed in WO 00/24883.

More than one copy of a polynucleotide of the present invention may beinserted into a host cell to increase production of a variant. Anincrease in the copy number of the polynucleotide can be obtained byintegrating at least one additional copy of the sequence into the hostcell genome or by including an amplifiable selectable marker gene withthe polynucleotide where cells containing amplified copies of theselectable marker gene, and thereby additional copies of thepolynucleotide, can be selected for by cultivating the cells in thepresence of the appropriate selectable agent.

The procedures used to ligate the elements described above to constructthe recombinant expression vectors of the present invention are wellknown to one skilled in the art (see, e.g., Sambrook et al., 1989,supra).

Host Cells

The present invention also relates to recombinant host cells, comprisinga polynucleotide encoding a variant of the present invention operablylinked to one or more control sequences that direct the production of avariant of the present invention. A construct or vector comprising apolynucleotide is introduced into a host cell so that the construct orvector is maintained as a chromosomal integrant or as a self-replicatingextra-chromosomal vector as described earlier. The term “host cell”encompasses any progeny of a parent cell that is not identical to theparent cell due to mutations that occur during replication. The choiceof a host cell will to a large extent depend upon the gene encoding thevariant and its source.

The host cell may be any cell useful in the recombinant production of avariant, e.g., a prokaryote or a eukaryote.

The prokaryotic host cell may be any Gram-positive or Gram-negativebacterium. Gram-positive bacteria include, but are not limited to,Bacillus, Clostridium, Enterococcus, Geobacillus, Lactobacillus,Lactococcus, Oceanobacillus, Staphylococcus, Streptococcus, andStreptomyces. Gram-negative bacteria include, but are not limited to,Campylobacter, E. coli, Flavobacterium, Fusobacterium, Helicobacter,Ilyobacter, Neisseria, Pseudomonas, Salmonella, and Ureaplasma.

The bacterial host cell may be any Bacillus cell including, but notlimited to, Bacillus alkalophilus, Bacillus amyloliquefaciens, Bacillusbrevis, Bacillus circulans, Bacillus clausii, Bacillus coagulans,Bacillus firmus, Bacillus lautus, Bacillus lentus, Bacilluslicheniformis, Bacillus megaterium, Bacillus pumilus, Bacillusstearothermophilus, Bacillus subtilis, and Bacillus thuringiensis cells.

The bacterial host cell may also be any Streptococcus cell including,but not limited to, Streptococcus equisimilis, Streptococcus pyogenes,Streptococcus uberis, and Streptococcus equi subsp. Zooepidemicus cells.

The bacterial host cell may also be any Streptomyces cell, including,but not limited to, Streptomyces achromogenes, Streptomyces avermitilis,Streptomyces coelicolor, Streptomyces griseus, and Streptomyces lividanscells.

The introduction of DNA into a Bacillus cell may be effected byprotoplast transformation (see, e.g., Chang and Cohen, 1979, Mol. Gen.Genet. 168: 111-115), competent cell transformation (see, e.g., Youngand Spizizen, 1961, J. Bacteriol. 81: 823-829, or Dubnau andDavidoff-Abelson, 1971, J. Mol. Biol. 56: 209-221), electroporation(see, e.g., Shigekawa and Dower, 1988, Biotechniques 6: 742-751), orconjugation (see, e.g., Koehler and Thorne, 1987, J. Bacteriol. 169:5271-5278). The introduction of DNA into an E. coli cell may be effectedby protoplast transformation (see, e.g., Hanahan, 1983, J. Mol. Biol.166: 557-580) or electroporation (see, e.g., Dower et al., 1988, NucleicAcids Res. 16: 6127-6145). The introduction of DNA into a Streptomycescell may be effected by protoplast transformation, electroporation (see,e.g., Gong et al., 2004, Folia Microbiol. (Praha) 49: 399-405),conjugation (see, e.g., Mazodier et al., 1989, J. Bacteriol. 171:3583-3585), or transduction (see, e.g., Burke et al., 2001, Proc. Natl.Acad. Sci. USA 98: 6289-6294). The introduction of DNA into aPseudomonas cell may be effected by electroporation (see, e.g., Choi etal., 2006, J. Microbiol. Methods 64: 391-397), or conjugation (see,e.g., Pinedo and Smets, 2005, Appl. Environ. Microbiol. 71: 51-57). Theintroduction of DNA into a Streptococcus cell may be effected by naturalcompetence (see, e.g., Perry and Kuramitsu, 1981, Infect. Immun. 32:1295-1297), protoplast transformation (see, e.g., Catt and Jollick,1991, Microbios 68: 189-207), electroporation (see, e.g., Buckley etal., 1999, Appl. Environ. Microbiol. 65: 3800-3804) or conjugation (see,e.g., Clewell, 1981, Microbiol. Rev. 45: 409-436). However, any methodknown in the art for introducing DNA into a host cell can be used.

The host cell may also be a eukaryote, such as a mammalian, insect,plant, or fungal cell.

The host cell may be a fungal cell. “Fungi” as used herein includes thephyla Ascomycota, Basidiomycota, Chytridiomycota, and Zygomycota as wellas the Oomycota and all mitosporic fungi (as defined by Hawksworth etal., In, Ainsworth and Bisby's Dictionary of The Fungi, 8th edition,1995, CAB International, University Press, Cambridge, UK).

The fungal host cell may be a yeast cell. “Yeast” as used hereinincludes ascosporogenous yeast (Endomycetales), basidiosporogenousyeast, and yeast belonging to the Fungi Imperfecti (Blastomycetes).Since the classification of yeast may change in the future, for thepurposes of this invention, yeast shall be defined as described inBiology and Activities of Yeast (Skinner, Passmore, and Davenport,editors, Soc. App. Bacteriol. Symposium Series No. 9, 1980).

The yeast host cell may be a Candida, Hansenula, Kluyveromyces, Pichia,Saccharomyces, Schizosaccharomyces, or Yarrowia cell such as aKluyveromyces lactis, Saccharomyces carlsbergensis, Saccharomycescerevisiae, Saccharomyces diastaticus, Saccharomyces douglasii,Saccharomyces kluyveri, Saccharomyces norbensis, Saccharomycesoviformis, or Yarrowia lipolytica cell.

The fungal host cell may be a filamentous fungal cell. “Filamentousfungi” include all filamentous forms of the subdivision Eumycota andOomycota (as defined by Hawksworth et al., 1995, supra). The filamentousfungi are generally characterized by a mycelial wall composed of chitin,cellulose, glucan, chitosan, mannan, and other complex polysaccharides.Vegetative growth is by hyphal elongation and carbon catabolism isobligately aerobic. In contrast, vegetative growth by yeasts such asSaccharomyces cerevisiae is by budding of a unicellular thallus andcarbon catabolism may be fermentative.

The filamentous fungal host cell may be an Acremonium, Aspergillus,Aureobasidium, Bjerkandera, Ceriporiopsis, Chrysosporium, Coprinus,Coriolus, Cryptococcus, Filibasidium, Fusarium, Humicola, Magnaporthe,Mucor, Myceliophthora, Neocallimastix, Neurospora, Paecilomyces,Penicillium, Phanerochaete, Phlebia, Piromyces, Pleurotus,Schizophyllum, Talaromyces, Thermoascus, Thielavia, Tolypocladium,Trametes, or Trichoderma cell.

Fungal cells may be transformed by a process involving protoplastformation, transformation of the protoplasts, and regeneration of thecell wall in a manner known per se. Suitable procedures fortransformation of Aspergillus and Trichoderma host cells are describedin EP238023, Yelton et al., 1984, Proc. Natl. Acad. Sci. USA 81:1470-1474, and Christensen et al., 1988, Bio/Technology 6: 1419-1422.Suitable methods for transforming Fusarium species are described byMalardier et al., 1989, Gene 78: 147-156, and WO 96/00787.

Methods of Production

The present invention also relates to methods of producing a variant,comprising: (a) cultivating a host cell of the present invention underconditions suitable for expression of the variant; and (b) recoveringthe variant.

The host cells are cultivated in a nutrient medium suitable forproduction of the variant using methods known in the art. For example,the cell may be cultivated by shake flask cultivation, or small-scale orlarge-scale fermentation (including continuous, batch, fed-batch, orsolid state fermentations) in laboratory or industrial fermentorsperformed in a suitable medium and under conditions allowing the variantto be expressed and/or isolated. The cultivation takes place in asuitable nutrient medium comprising carbon and nitrogen sources andinorganic salts, using procedures known in the art. Suitable media areavailable from commercial suppliers or may be prepared according topublished compositions (e.g., in catalogues of the American Type CultureCollection). If the variant is secreted into the nutrient medium, thevariant can be recovered directly from the medium. If the variant is notsecreted, it can be recovered from cell lysates.

The variant may be detected using methods known in the art that arespecific for the variants. These detection methods include, but are notlimited to, use of specific antibodies, formation of an enzyme product,or disappearance of an enzyme substrate. For example, an enzyme assaymay be used to determine the activity of the variant may be the assaydescribed in the examples below.

The variant may be recovered using methods known in the art. Forexample, the variant may be recovered from the nutrient medium byconventional procedures including, but not limited to, collection,centrifugation, filtration, extraction, spray-drying, evaporation, orprecipitation.

The variant may be purified by a variety of procedures known in the artincluding, but not limited to, chromatography (e.g., ion exchange,affinity, hydrophobic, chromatofocusing, and size exclusion),electrophoretic procedures (e.g., preparative isoelectric focusing),differential solubility (e.g., ammonium sulfate precipitation),SDS-PAGE, or extraction (see, e.g., Protein Purification, Janson andRyden, editors, VCH Publishers, New York, 1989) to obtain substantiallypure variants.

In an alternative aspect, the variant is not recovered, but rather ahost cell of the present invention expressing the variant is used as asource of the variant.

Soap—

The compositions herein may contain soap. Without being limited bytheory, it may be desirable to include soap as it acts in part as asurfactant and in part as a builder and may be useful for suppression offoam and may furthermore interact favorably with the various cationiccompounds of the composition to enhance softness on textile fabricstreaded with the inventive compositions. Any soap known in the art foruse in laundry detergents may be utilized. In one embodiment, thecompositions contain from 0 wt % to 20 wt %, from 0.5 wt % to 20 wt %,from 4 wt % to 10 wt %, or from 4 wt % to 7 wt % of soap.

Examples of soap useful herein include oleic acid soaps, palmitic acidsoaps, palm kernel fatty acid soaps, and mixtures thereof. Typical soapsare in the form of mixtures of fatty acid soaps having different chainlengths and degrees of substitution. One such mixture is topped palmkernel fatty acid.

Hydrotropes—

The compositions of the present invention may comprise one or morehydrotropes. A hydrotrope is a compound that solubilises hydrophobiccompounds in aqueous solutions (or oppositely, polar substances in anon-polar environment). Typically, hydrotropes have both hydrophilic anda hydrophobic character (so-called amphiphilic properties as known fromsurfactants); however the molecular structure of hydrotropes generallydo not favor spontaneous self-aggregation, see e.g. review by Hodgdonand Kaler (2007), Current Opinion in Colloid & Interface Science 12:121-128. Hydrotropes do not display a critical concentration above whichself-aggregation occurs as found for surfactants and lipids formingmiceller, lamellar or other well defined meso-phases. Instead, manyhydrotropes show a continuous-type aggregation process where the sizesof aggregates grow as concentration increases. However, many hydrotropesalter the phase behavior, stability, and colloidal properties of systemscontaining substances of polar and non-polar character, includingmixtures of water, oil, surfactants, and polymers. Hydrotropes areclassically used across industries from pharma, personal care, food, totechnical applications. Use of hydrotropes in detergent compositionsallow for example more concentrated formulations of surfactants (as inthe process of compacting liquid detergents by removing water) withoutinducing undesired phenomena such as phase separation or high viscosity.

The detergent may contain from 0 to 10 wt %, such as from 0 to 5 wt %,0.5 to 5 wt %, or from 3% to 5 wt %, of a hydrotrope. Any hydrotropeknown in the art for use in detergents may be utilized.

Form of the Composition

The compositions described herein are advantageously employed forexample, in laundry applications, hard surface cleaning, dishwashingapplications, as well as cosmetic applications such as dentures, teeth,hair and skin. The compositions of the invention are in particular solidor liquid cleaning and/or treatment compositions. In one aspect theinvention relates to a composition, wherein the form of the compositionis selected from the group consisting of a regular, compact orconcentrated liquid; a gel; a paste; a soap bar; a regular or acompacted powder; a granulated solid; a homogenous or a multilayertablet with two or more layers (same or different phases); a pouchhaving one or more compartments; a single or a multi-compartment unitdose form; or any combination thereof.

The form of the composition may separate the components physically fromeach other in compartments such as e.g. water dissolvable pouches or indifferent layers of tablets. Thereby negative storage interactionbetween components can be avoided. Different dissolution profiles ofeach of the compartments can also give rise to delayed dissolution ofselected components in the wash solution.

Pouches can be configured as single or multicompartments. It can be ofany form, shape and material which is suitable for hold the composition,e.g. without allowing the release of the composition to release of thecomposition from the pouch prior to water contact. The pouch is madefrom water soluble film which encloses an inner volume. Said innervolume can be divided into compartments of the pouch. Preferred filmsare polymeric materials preferably polymers which are formed into a filmor sheet. Preferred polymers, copolymers or derivates thereof areselected polyacrylates, and water soluble acrylate copolymers, methylcellulose, carboxy methyl cellulose, sodium dextrin, ethyl cellulose,hydroxyethyl cellulose, hydroxypropyl methyl cellulose, malto dextrin,poly methacrylates, most preferably polyvinyl alcohol copolymers and,hydroxypropyl methyl cellulose (HPMC). Preferably the level of polymerin the film for example PVA is at least about 60%. Preferred averagemolecular weight will typically be about 20,000 to about 150,000.

The pouches cancomprise a solid laundry cleaning composition or part components and/ora liquid cleaning composition or part components separated by the watersoluble film. The compartment for liquid components can be different incomposition than compartments containing solids (US2009/0011970 A1).

Lipase Particles

The lipase variants comprised in the water-soluble film of the inventionmay be present as lipase particles. The lipase particles may evencontain one or more Additional Enzymes, as described below.

Lipase particles are any form of lipase variant in a solid particulateform. That can be as lipase crystals, lipase precipitate, spray orfreeze-dried lipase or any form of granulated lipase, either as a powderor a suspension in liquid. Typically the particle size, measured asequivalent spherical diameter (volume based average particle size), ofthe lipase particles is below 2 mm, preferably below 1 mm, below 0.5 mm,below 0.25 mm, or below 0.1 mm; and above 0.05 μm, preferably above 0.1μm, above 0.5 μm, above 1 μm, above 5 μm or above 10 μm.

In a preferred embodiment, the particle size of the lipase particles isfrom 0.5 μm to 100 μm.

The lipase particles contain at least 1% w/w lipase protein, preferablyat least 5% w/w lipase protein, at least 10% w/w lipase protein, atleast 20% w/w lipase protein, at least 30% w/w lipase protein, at least40% w/w lipase protein, at least 50% w/w lipase protein, at least 60%w/w lipase protein, at least 70% w/w lipase protein, at least 80% w/wlipase protein, or at least 90% w/w lipase protein.

Enzyme crystallization may be carried out in a number of ways, as knownin the art (e.g., as described in WO91/09943 or WO94/22903).

The lipase may be formulated in the lipase particle as known in the artfor solid enzyme formulations, such as formulations for reducing dust,improving stability and/or modifying relase rate of the enzyme. Thelipase particle may also be formulated in a matrix or coated with agentssuppressing dissolution of the enzyme particle in the PVOH/film solutionused for preparing the water-soluble film.

The lipase molecules on the surface of the lipase particles may also becross-linked, like CLECs (Cross-Linked Enzyme Crystals) or CLEA(Cross-Linked Enzyme Aggregate).

Water-Soluble Film

Water-soluble films, optional ingredients for use therein, and methodsof making the same are well known in the art. In one class ofembodiments, the water-soluble film includes PVOH. PVOH is a syntheticresin generally prepared by the alcoholysis, usually termed hydrolysisor saponification, of polyvinyl acetate. Fully hydrolyzed PVOH, whereinvirtually all the acetate groups have been converted to alcohol groups,is a strongly hydrogen-bonded, highly crystalline polymer whichdissolves only in hot water—greater than about 140° F. (60° C.). If asufficient number of acetate groups are allowed to remain after thehydrolysis of polyvinyl acetate, the PVOH polymer then being known aspartially hydrolyzed, it is more weakly hydrogen-bonded and lesscrystalline and is soluble in cold water—less than about 50° F. (10°C.). An intermediate cold/hot water-soluble film can include, forexample, intermediate partially-hydrolyzed PVOH (e.g., with degrees ofhydrolysis of about 94% to about 98%), and is readily soluble only inwarm water—e.g., rapid dissolution at temperatures of about 40° C. andgreater. Both fully and partially hydrolyzed PVOH types are commonlyreferred to as PVOH homopolymers although the partially hydrolyzed typeis technically a vinyl alcohol-vinyl acetate copolymer.

The degree of hydrolysis of the PVOH included in the water-soluble filmsof the present disclosure can be about 75% to about 99%. As the degreeof hydrolysis is reduced, a film made from the resin will have reducedmechanical strength but faster solubility at temperatures below about20° C. As the degree of hydrolysis increases, a film made from the resinwill tend to be mechanically stronger and the thermoformability willtend to decrease. The degree of hydrolysis of the PVOH can be chosensuch that the water-solubility of the resin is temperature dependent,and thus the solubility of a film made from the resin, compatibilizingagent, and additional ingredients is also influenced. In one class ofembodiments the film is cold water-soluble. A cold water-soluble film,soluble in water at a temperature of less than 10° C., can include PVOHwith a degree of hydrolysis in a range of about 75% to about 90%, or ina range of about 80% to about 90%, or in a range of about 85% to about90%. In another class of embodiments the film is hot water-soluble. Ahot water-soluble film, soluble in water at a temperature of at leastabout 60° C., can include PVOH with a degree of hydrolysis of at leastabout 98%.

Other film-forming resins for use in addition to or in an alternative toPVOH can include, but are not limited to, modified polyvinyl alcohols,polyacrylates, water-soluble acrylate copolymers, polyacrylates,polyacryamides, polyvinyl pyrrolidone, pullulan, water-soluble naturalpolymers including, but not limited to, guar gum, xanthan gum,carrageenan, and starch, water-soluble polymer derivatives including,but not limited to, ethoxylated starch and hydroxypropylated starch,poly(sodium acrylamido-2-methylpropane sulfonate),polymonomethylmaleate, copolymers thereof, and combinations of any ofthe foregoing. In one class of embodiments, the film-forming resin is aterpolymer consisting of vinyl alcohol, vinyl acetate, and sodiumacrylamido-2-methylpropanesulfonate. Unexpectedly, water-soluble filmsbased on a vinyl alcohol, vinyl acetate, and sodiumacrylamido-2-methylpropanesulfonate terpolymer have demonstrated a highpercent recovery of enzyme.

The water-soluble resin can be included in the water-soluble film in anysuitable amount, for example an amount in a range of about 35 wt % toabout 90 wt %. The preferred weight ratio of the amount of thewater-soluble resin as compared to the combined amount of all enzymes,enzyme stabilizers, and secondary additives can be any suitable ratio,for example a ratio in a range of about 0.5 to about 5, or about 1 to 3,or about 1 to 2.

Water-soluble resins for use in the films described herein (including,but not limited to PVOH resins) can be characterized by any suitableviscosity for the desired film properties, optionally a viscosity in arange of about 5.0 to about 30.0 cP, or about 10.0 cP to about 25 cP.The viscosity of a PVOH resin is determined by measuring a freshly madesolution using a Brookfield LV type viscometer with UL adapter asdescribed in British Standard EN ISO 15023-2:2006 Annex E BrookfieldTest method. It is international practice to state the viscosity of 4%aqueous polyvinyl alcohol solutions at 20° C. All PVOH viscositiesspecified herein in cP should be understood to refer to the viscosity of4% aqueous polyvinyl alcohol solution at 20° C., unless specifiedotherwise.

It is well known in the art that the viscosity of a PVOH resin iscorrelated with the weight average molecular weight (Mw) of the samePVOH resin, and often the viscosity is used as a proxy for Mw. Thus, theweight average molecular weight of the water-soluble resin optionallycan be in a range of about 35,000 to about 190,000, or about 80,000 toabout 160,000. The molecular weight of the resin need only be sufficientto enable it to be molded by suitable techniques to form a thin plasticfilm.

The water-soluble films according to the present disclosure may includeother optional additive ingredients including, but not limited to,plasticizers, surfactants, defoamers, film formers, antiblocking agents,internal release agents, anti-yellowing agents and other functionalingredients, for example in amounts suitable for their intended purpose.

Water is recognized as a very efficient plasticizer for PVOH and otherpolymers; however, the volatility of water makes its utility limitedsince polymer films need to have at least some resistance (robustness)to a variety of ambient conditions including low and high relativehumidity. Glycerin is much less volatile than water and has been wellestablished as an effective plasticizer for PVOH and other polymers.Glycerin or other such liquid plasticizers by themselves can causesurface “sweating” and greasiness if the level used in the filmformulation is too high. This can lead to problems in a film such asunacceptable feel to the hand of the consumer and even blocking of thefilm on the roll or in stacks of sheets if the sweating is not mitigatedin some manner, such as powdering of the surface. This could becharacterized as over plasticization. However, if too little plasticizeris added to the film the film may lack sufficient ductility andflexibility for many end uses, for example to be converted into a finaluse format such as pouches.

Plasticizers for use in water-soluble films of the present disclosureinclude, but are not limited to, sorbitol, glycerol, diglycerol,propylene glycol, ethylene glycol, diethyleneglycol, triethylene glycol,tetraethyleneglycol, polyethylene glycols up to MW 400, 2 methyl 1,3propane diol, lactic acid, monoacetin, triacetin, triethyl citrate,1,3-butanediol, trimethylolpropane (TMP), polyether triol, andcombinations thereof. Polyols, as described above, are generally usefulas plasticizers. As less plasticizer is used, the film can become morebrittle, whereas as more plasticizer is used the film can lose tensilestrength. Plasticizers can be included in the water-soluble films in anamount in a range of about 25 phr to about 50 phr, or from about 30 phrto about 45 phr, or from about 32 phr to about 42 phr, for example.

Surfactants for use in water-soluble films are well known in the art.Optionally, surfactants are included to aid in the dispersion of theresin solution upon casting. Suitable surfactants for water-solublefilms of the present disclosure include, but are not limited to, dialkylsulfosuccinates, lactylated fatty acid esters of glycerol and propyleneglycol, lactylic esters of fatty acids, sodium alkyl sulfates,polysorbate 20, polysorbate 60, polysorbate 65, polysorbate 80, alkylpolyethylene glycol ethers, lecithin, acetylated fatty acid esters ofglycerol and propylene glycol, sodium lauryl sulfate, acetylated estersof fatty acids, myristyl dimethylamine oxide, trimethyl tallow alkylammonium chloride, quaternary ammonium compounds, salts thereof andcombinations of any of the forgoing. Thus, surfactants can be includedin the water-soluble films in an amount of less than about 2 phr, forexample less than about 1 phr, or less than about 0.5 phr, for example.

One type of secondary component contemplated for use is a defoamer.Defoamers can aid in coalescing of foam bubbles. Suitable defoamers foruse in water-soluble films according to the present disclosure include,but are not limited to, hydrophobic silicas, for example silicon dioxideor fumed silica in fine particle sizes, including Foam Blast® defoamersavailable from Emerald Performance Materials, including Foam Blast® 327,Foam Blast® UVD, Foam Blast® 163, Foam Blast® 269, Foam Blast® 338, FoamBlast® 290, Foam Blast® 332, Foam Blast® 349, Foam Blast® 550 and FoamBlast® 339, which are proprietary, non-mineral oil defoamers. Inembodiments, defoamers can be used in an amount of 0.5 phr, or less, forexample, 0.05 phr, 0.04 phr, 0.03 phr, 0.02 phr, or 0.01 phr.Preferably, significant amounts of silicon dioxide will be avoided, inorder to avoid stress whitening.

Processes for making water-soluble articles, including films, includecasting, blow-molding, extrusion and blown extrusion, as known in theart. One contemplated class of embodiments is characterized by thewater-soluble film described herein being formed by casting, forexample, by admixing the ingredients described herein with water tocreate an aqueous mixture, for example a solution with optionallydispersed solids, applying the mixture to a surface, and drying offwater to create a film. Similarly, other compositions can be formed bydrying the mixture while it is confined in a desired shape.

In one contemplated class of embodiments, the water-soluble film isformed by casting a water-soluble mixture wherein the water-solublemixture is prepared according to the steps of:

-   (a) providing a mixture of water-soluble resin, water, and any    optional additives excluding plasticizers;-   (b) boiling the mixture for 30 minutes;-   (c) degassing the mixture in an oven at a temperature of at least    40° C.; optionally in a range of 40° C. to 70° C., e.g., about 65°    C.;-   (d) adding one or more enzymes, plasticizer, and additional water to    the mixture at a temperature of 65° C. or less; and-   (e) stirring the mixture without vortex until the mixture appears    substantially uniform in color and consistency; optionally for a    time period in a range of 30 minutes to 90 minutes, optionally at    least 1 hour; and-   (f) casting the mixture promptly after the time period of stirring    (e.g., within 4 hours, or 2 hours, or 1 hour).

If the enzyme is added to the mixture too early, e.g., with thesecondary additives or resin, the activity of the enzyme may decrease.Without intending to be bound by any particular theory, it is believedthat boiling of the mixture with the enzyme leads to the enzymedenaturing and storing in solution for extended periods of time alsoleads to a reduction in enzyme activity.

In one class of embodiments, high enzyme activity is maintained in thewater-soluble films according to the present disclosure by drying thefilms quickly under moderate to mild conditions. As used herein, dryingquickly refers to a drying time of less than 24 hours, optionally lessthan 12 hours, optionally less than 8 hours, optionally less than 2hours, optionally less than 1 hour, optionally less than 45 minutes,optionally less than 30 minutes, optionally less than 20 minutes,optionally less than 10 minutes, for example in a range of about 6minutes to about 10 minutes, or 8 minutes. As used herein, moderate tomild conditions refer to drying temperatures of less than 170° F. (77°C.), optionally in a range of about 150° F. to about 170° F. (about 66°C. to about 77° C.), e.g., 165° F. (74° C.). As the drying temperatureincreases, the enzymes tend to denature faster, whereas as the dryingtemperature decreases, the drying time increases, thus exposing theenzymes to solution for an extended period of time.

The film is useful for creating a packet to contain a composition, forexample laundry or dishwashing compositions, thereby forming a pouch.The film described herein can also be used to make a packet with two ormore compartments made of the same film or in combination with films ofother polymeric materials. Additional films can, for example, beobtained by casting, blow-molding, extrusion or blown extrusion of thesame or a different polymeric material, as known in the art. In one typeof embodiment, the polymers, copolymers or derivatives thereof suitablefor use as the additional film are selected from polyvinyl alcohols,polyvinyl pyrrolidone, polyalkylene oxides, polyacrylic acid, cellulose,cellulose ethers, cellulose esters, cellulose amides, polyvinylacetates, polycarboxylic acids and salts, polyaminoacids or peptides,polyamides, polyacrylamide, copolymers of maleic/acrylic acids,polysaccharides including starch and gelatin, natural gums such asxanthan, and carrageenans. For example, polymers can be selected frompolyacrylates and water-soluble acrylate copolymers, methylcellulose,carboxymethylcellulose sodium, dextrin, ethylcellulose, hydroxyethylcellulose, hydroxypropyl methylcellulose, maltodextrin,polymethacrylates, and combinations thereof, or selected from polyvinylalcohols, polyvinyl alcohol copolymers and hydroxypropyl methylcellulose (HPMC), and combinations thereof.

The pouches and/or packets of the present disclosure comprise at leastone sealed compartment. Thus the pouches may comprise a singlecompartment or multiple compartments. The pouches may have regions withand without enzymes. In embodiments including multiple compartments,each compartment may contain identical and/or different compositions. Inturn, the compositions may take any suitable form including, but notlimited to liquid, solid and combinations thereof (e.g., a solidsuspended in a liquid). In some embodiments, the pouches comprises afirst, second and third compartment, each of which respectively containsa different first, second and third composition. In some embodiments,the compositions may be visually distinct as described in EP 2258820.

The compartments of multi-compartment pouches and/or packets may be ofthe same or different size(s) and/or volume(s). The compartments of thepresent multi-compartment pouches can be separate or conjoined in anysuitable manner. In some embodiments, the second and/or third and/orsubsequent compartments are superimposed on the first compartment. Inone embodiment, the third compartment may be superimposed on the secondcompartment, which is in turn superimposed on the first compartment in asandwich configuration. Alternatively the second and third compartmentsmay be superimposed on the first compartment. However it is also equallyenvisaged that the first, second and optionally third and subsequentcompartments may be attached to one another in a side by siderelationship. The compartments may be packed in a string, eachcompartment being individually separable by a perforation line. Henceeach compartment may be individually torn-off from the remainder of thestring by the end-user.

In some embodiments, multi-compartment pouches and/or packets includethree compartments consisting of a large first compartment and twosmaller compartments. The second and third smaller compartments aresuperimposed on the first larger compartment. The size and geometry ofthe compartments are chosen such that this arrangement is achievable.The geometry of the compartments may be the same or different. In someembodiments the second and optionally third compartment each has adifferent geometry and shape as compared to the first compartment. Inthese embodiments, the second and optionally third compartments arearranged in a design on the first compartment. The design may bedecorative, educative, or illustrative, for example to illustrate aconcept or instruction, and/or used to indicate origin of the product.In some embodiments, the first compartment is the largest compartmenthaving two large faces sealed around the perimeter, and the secondcompartment is smaller covering less than about 75%, or less than about50% of the surface area of one face of the first compartment. Inembodiments in which there is a third compartment, the aforementionedstructure may be the same but the second and third compartments coverless than about 60%, or less than about 50%, or less than about 45% ofthe surface area of one face of the first compartment.

The pouches and/or packets of the present disclosure may comprise one ormore different films. For example, in single compartment embodiments,the packet may be made from one wall that is folded onto itself andsealed at the edges, or alternatively, two walls that are sealedtogether at the edges. In multiple compartment embodiments, the packetmay be made from one or more films such that any given packetcompartment may comprise walls made from a single film or multiple filmshaving differing compositions. In one embodiment, a multi-compartmentpouch comprises at least three walls: an outer upper wall; an outerlower wall; and a partitioning wall. The outer upper wall and the outerlower wall are generally opposing and form the exterior of the pouch.The partitioning wall is interior to the pouch and is secured to thegenerally opposing outer walls along a seal line. The partitioning wallseparates the interior of the multi-compartment pouch into at least afirst compartment and a second compartment. In one class of embodiments,the partitioning wall may be the only enzyme containing film therebyminimizing the exposure of the consumer to the enzymes.

Pouches and packets may be made using any suitable equipment and method.For example, single compartment pouches may be made using vertical formfilling, horizontal form filling, or rotary drum filling techniquescommonly known in the art. Such processes may be either continuous orintermittent. The film may be dampened, and/or heated to increase themalleability thereof. The method may also involve the use of a vacuum todraw the film into a suitable mold. The vacuum drawing the film into themold can be applied for about 0.2 to about 5 seconds, or about 0.3 toabout 3, or about 0.5 to about 1.5 seconds, once the film is on thehorizontal portion of the surface. This vacuum can be such that itprovides an under-pressure in a range of 10 mbar to 1000 mbar, or in arange of 100 mbar to 600 mbar, for example.

The molds, in which packets may be made, can have any shape, length,width and depth, depending on the required dimensions of the pouches.The molds may also vary in size and shape from one to another, ifdesirable. For example, the volume of the final pouches may be about 5ml to about 300 ml, or about 10 to 150 ml, or about 20 to about 100 ml,and that the mold sizes are adjusted accordingly.

In one embodiment, the packet includes a first and a second sealedcompartment. The second compartment is in a generally superposedrelationship with the first sealed compartment such that the secondsealed compartment and the first sealed compartment share a partitioningwall interior to the pouch.

In one embodiment, the packet including a first and a second compartmentfurther includes a third sealed compartment. The third sealedcompartment is in a generally superposed relationship with the firstsealed compartment such that the third sealed compartment and the firstsealed compartment share a partitioning wall interior to the pouch.

In various embodiments, the first composition and the second compositionare selected from one of the following combinations: liquid, liquid;liquid, powder; powder, powder; and powder, liquid.

In various embodiments, the first, second and third compositions areselected from one of the following combinations: solid, liquid, liquidand liquid, liquid, liquid.

In one embodiment, the single compartment or plurality of sealedcompartments contains a composition. The plurality of compartments mayeach contain the same or a different composition. The composition isselected from a liquid, solid or combination thereof.

Heat can be applied to the film in the process commonly known asthermoforming. The heat may be applied using any suitable means. Forexample, the film may be heated directly by passing it under a heatingelement or through hot air, prior to feeding it onto a surface or onceon a surface. Alternatively, it may be heated indirectly, for example byheating the surface or applying a hot item onto the film. The film canbe heated using an infrared light. The film may be heated to atemperature of at least 50° C., for example about 50 to about 150° C.,about 50 to about 120° C., about 60 to about 130° C., about 70 to about120° C., or about 60 to about 90° C.

Alternatively, the film can be wetted by any suitable means, for exampledirectly by spraying a wetting agent (including water, a solution of thefilm composition, a plasticizer for the film composition, or anycombination of the foregoing) onto the film, prior to feeding it ontothe surface or once on the surface, or indirectly by wetting the surfaceor by applying a wet item onto the film.

Once a film has been heated and/or wetted, it may be drawn into anappropriate mold, preferably using a vacuum. The film can bethermoformed with a draw ratio of at least about 1.5, for example, andoptionally up to a draw ratio of 2, for example. The filling of themolded film can be accomplished by utilizing any suitable means. In someembodiments, the most preferred method will depend on the product formand required speed of filling. In some embodiments, the molded film isfilled by in-line filling techniques. The filled, open packets are thenclosed forming the pouches, using a second film, by any suitable method.This may be accomplished while in horizontal position and in continuous,constant motion. The closing may be accomplished by continuously feedinga second film, preferably water-soluble film, over and onto the openpackets and then preferably sealing the first and second film together,typically in the area between the molds and thus between the packets.

Any suitable method of sealing the packet and/or the individualcompartments thereof may be utilized. Non-limiting examples of suchmeans include heat sealing, solvent welding, solvent or wet sealing, andcombinations thereof. The water-soluble packet and/or the individualcompartments thereof can be heat sealed at a temperature of at least200° F. (93° C.), for example in a range of about 220° F. (about 105°C.) to about 290° F. (about 145° C.), or about 230° F. (about 110° C.)to about 280° F. (about 140° C.). Typically, only the area which is toform the seal is treated with heat or solvent. The heat or solvent canbe applied by any method, typically on the closing material, andtypically only on the areas which are to form the seal. If solvent orwet sealing or welding is used, it may be preferred that heat is alsoapplied. Preferred wet or solvent sealing/welding methods includeselectively applying solvent onto the area between the molds, or on theclosing material, by for example, spraying or printing this onto theseareas, and then applying pressure onto these areas, to form the seal.Sealing rolls and belts as described above (optionally also providingheat) can be used, for example.

The formed pouches may then be cut by a cutting device. Cutting can beaccomplished using any known method. It may be preferred that thecutting is also done in continuous manner, and preferably with constantspeed and preferably while in horizontal position. The cutting devicecan, for example, be a sharp item, or a hot item, or a laser, whereby inthe latter cases, the hot item or laser ‘burns’ through the film/sealingarea.

The different compartments of a multi-compartment pouches may be madetogether in a side-by-side style wherein the resulting, cojoined pouchesmay or may not be separated by cutting. Alternatively, the compartmentscan be made separately.

In some embodiments, pouches may be made according to a processincluding the steps of:

-   a) forming a first compartment (as described above);-   b) forming a recess within some or all of the closed compartment    formed in step (a), to generate a second molded compartment    superposed above the first compartment;-   c) filling and closing the second compartments by means of a third    film;-   d) sealing the first, second and third films; and-   e) cutting the films to produce a multi-compartment pouch.

The recess formed in step (b) may be achieved by applying a vacuum tothe compartment prepared in step (a).

In some embodiments, second, and/or third compartment(s) can be made ina separate step and then combined with the first compartment asdescribed in EP 2088187 or WO 2009/152031.

In other embodiments, pouches may be made according to a processincluding the steps of:

-   a) forming a first compartment, optionally using heat and/or vacuum,    using a first film on a first forming machine;-   b) filling the first compartment with a first composition;-   c) on a second forming machine, deforming a second film, optionally    using heat and vacuum, to make a second and optionally third molded    compartment;-   d) filling the second and optionally third compartments;-   e) sealing the second and optionally third compartment using a third    film;-   f) placing the sealed second and optionally third compartments onto    the first compartment;-   g) sealing the first, second and optionally third compartments; and-   h) cutting the films to produce a multi-compartment pouch.

The first and second forming machines may be selected based on theirsuitability to perform the above process. In some embodiments, the firstforming machine is preferably a horizontal forming machine, and thesecond forming machine is preferably a rotary drum forming machine,preferably located above the first forming machine.

It should be understood that by the use of appropriate feed stations, itmay be possible to manufacture multi-compartment pouches incorporating anumber of different or distinctive compositions and/or different ordistinctive liquid, gel or paste compositions.

Cellulose (Avicel) was coated with a mixture of triglyceride and4-methylumbelliferyl oleate (4-MU oleate) in an initial substratepreparation step. In the assay, the coated cellulose fibers weresuspended in a buffer, a detergent solution, and a lipase solution. Thelipase activity monitored in the cellulose suspension by measuring thefluorescence of released 4-methylumbelliferone (4-MU) at Ex: 365 nm andEm: 445 nm as a function of time.

Chemicals:

-   4-methylumbelliferyl oleate (oleic acid 4-methylumbelliferyl ester,    Sigma Aldrich 75164)-   n-Hexane (Sigma-Aldrich 15671)-   Olive oil (Sigma-Aldrich O-1514)-   Cellulose cotton linters, Avicel H-101 (Sigma-Aldrich 11365) HEPES    (4-(2-Hydroxyethyl)piperazine-1-ethanesulfonic acid,    N-(2-Hydroxyethyl)piperazine-N′-(2-ethanesulfonic acid,    Sigma-Aldrich H33759)-   Calcium chloride dihydrate-   Triton™ X-100 (4-(1,1,3,3-Tetramethylbutyl)phenyl-polyethylene    glycol, t-Octyl phenoxypolyethoxyethanol, Polyethylene glycol    tert-octylphenyl etherSigma-Aldrich T9284)-   4 mol/L NaOH (Fluka 35274)-   Model Detergent

Coated cellulose fibers were prepared by pipetting 668 uL 4-MU-oleatestock solution (4 mg/mL 4-Methylumbelliferyl oleate in hexane) and 3.03mL olive oil stock solution into 100 mL hexane in a round bottomed flaskfor rotational evaporator, and mixed properly before 10 g cellulosefibers was added. The flask was mounted on a rotational evaporator, andhexane was removed by evaporation at reduced pressure and constantmixing (by rotation) to ensure uniformly coating of the substrate on thecellulose. After complete removal of hexane, the coated cellulose fiberswere transferred to a brown flask and the material was stored protectedfrom light at −20° C. until use.

The assay was conducted by transferring 80 uL of Substrate suspension toeach well in a black micro-well microtiter plate (e.g. Nunclon surface,96 well black plates with black bottom, NUNC 137101). It is important tokeep a constant, thorough mixing of the Substrate suspension whenpipetting to ensure that the same amount of coated cellulose fibers aretransferred to each well of the microtiter plate. 10 uL of the Detergentworking solution was added to the wells.

The assay was started with addition of 10 uL of culture supernatants ofvariants or wild-type controls. The enzyme (supernatant) should be addedimmediately after addition of the Detergent working solution (1.65 gModel J Detergent (DC-2012-0057-6); adjust to 50 mL with Milli Q water).For the blank, 10 uL Lipase dilution buffer (200 mM HEPES; 1 mM CaCl2;10 ppm Triton X-100; adjusted to pH 8.3 with 4M NaOH) was added.

The enzyme activity was followed by measuring the fluorescence (kineticmode) every 30 seconds at Ex: 365 nm and Em: 445 nm from 1 to 6 minutesafter enzyme addition. The plate was mixed by shaking for 5 secondsbefore first measurement but not between the following measurements. Theassay was run at room temperature, i.e. approximately at 23° C.

The activity was calculated as the slope of a plot of fluorescenceversus time (units: RFS/minute, where RFS is the Relative FlourescenceSignal) using the 1-6 minute time window.

Improvement Factor

The improvement factor (IF) correlates the performance of a variantenzyme with that of the reference enzyme at the same proteinconcentration. Calculation of the improvement factor based on ResidualActivity (RA) were done according to the following equaition: IF=(RA ofthe variant)/(RA of the Wildtype). Calculation of the improvement factorbased on RFS/minute were done according to the following equaition:IF=(RFS of the variant)/(RFS of the Wildtype).

An improvement factor that is greater than 1 (IF>1) indicates animproved performance by a variant as compared to the reference, while aIF of 1 (IF=1) identifies a variant that performes the same as thereference, and an IF of less than 1 (IF<1) identifies a variant thatperforms worse that the reference.

Site-saturation libraries (SSL) were generated using Splicing by OverlapExtension PCR (SOE PCR) in each mentioned position in the RmL gene.Three PCR reactions were involved: 1) Generation of N-terminal fragmentwith the flanking N-terminal forward primer and the reverse mutagenicprimer; 2) Generation of C-terminal fragment with flanking C-terminalreverse primer and mutagenic forward primer which had a region ofcomplementarity to the reverse mutagenic primer; and 3) SOE PCR withDpnI digested and purified N- and C-fragments. The polymerase used forthe PCR reaction was Phusion DNA polymerase (Finnzymes, Cat. No.: F530L.DpnI was from New England Biolabs (Cat. No.: R0176S).

The SOE PCR product was purified and transformed in to the Aspergillushost, where site-specific homologous recombination in the Aspergilluschromosome took place.

Colonies picked from the transformed plate were inoculated in 96-wellculture plates (Nunc cat. No. 260887) containing M400 media (50 g/LMaltodextrin; 2 g/L Magnesium sulfate; 2 g/L Potassium dihydrogenphosphate; 4 g/L Citric acid monohydrous; 8 g/L Yeast Extract; 2 g/LUrea; 0.5 ml/L tracemetal (KU6) solution; and 0.5 g/L Calcium chloride)and grown at 34° C. for 4 days. Supernatants were recovered from theplates by centrifugation and were used for all the assays.

The position and mutation of the SSL variants were verified by standardsequencing.
